ABSTRACT:
The present invention relates to the use in a silica-filled rubber composition of an aminosilane compound of the formula ##STR1## wherein R.sup.1, R.sup.2 and R.sup.3 are independently selected from the group consisting of alkoxy radicals having from 1 to 8 carbon atoms, alkyl radicals having 1 to 8 carbon atoms and aryl radicals having 6 carbon atoms, with the proviso that at least one of R.sup.1, R.sup.2 and R.sup.3 is an alkoxy radical; R.sup.4 is selected from the group consisting of alkylene groups having from 1 to 18 carbon atoms and arylene and alkyl substituted arylene groups having from 6 to 10 carbon atoms; R.sup.5 is selected from the group consisting of hydrogen and alkyl groups having from 1 to 15 carbon atoms.
